Geologists have detected a unique chemical signature, a deficit of potassium-40, in ancient mantle rocks. This anomaly suggests that remnants of "proto-Earth," material predating our planet's ...

When we look at the solid ground beneath our feet, it's easy to assume Earth has always been this way. But our planet tells a story so extraordinary, so ...

New research sheds light on the earliest days of the earth's formation and potentially calls into question some earlier assumptions in planetary science about the early years of rocky planets.

The origin of life on Earth is still enigmatic, but we are slowly unraveling the steps involved and the necessary ingredients. Scientists believe life arose in a primordial soup of organic chemicals ...

A fresh look at past data reveals that exoplanets with masses similar to Jupiter formed much sooner than previously thought, according to new research. The Ohio State University study's results ...

Earth’s surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H2O), nitrogen (in atmospheric N2) and carbon (mainly in carbonate rocks). H, N and C are sometimes ...

The Earth is thought to have formed about 4.5 billion years ago. While life may have arisen about half a billion years later, the planet's magnetic field was not sufficient to protect the Earth, and ...

Old crystals found in Western Australia are drawing fresh attention from geologists studying the formation of Earth. These minerals, called zircons, have been dated to be older than four billion years ...

A study published in the journal Earth and Planetary Science Letters posits that Mars formed in what today is the Asteroid Belt, roughly one and a half times as far from the sun as its current ...
